  1. Zombie, or senescent, cells accumulate in our body with age, when we become less able to clear them. But a study in mice suggests that a drug could restore this ability and improve ageing outcomes #science #aging #senescence

  2. Disposable soma theory of aging (Evolution 🧬)

    In biogerontology, the disposable soma theory of aging states that organisms age due to an evolutionary trade-off between growth, reproduction, and DNA repair maintenance. Formulated by British biologist Thomas Kirkwood, the disposable soma theory explains that an organism only has a limited amount of...

  3. A quotation from Thoreau

    Age is no better, hardly so well, qualified for an instructor as youth, for it has not profited so much as it has lost.

    Henry David Thoreau (1817-1862) American philosopher and writer
    Walden; or, Life in the Woods, ch. 1 “Economy” (1854)

  4. Another excellent essay from Shanaka Anslem Perera. No idea where he finds the time to be this prolific, at this depth, but I'm very glad that he does.

    A theory on failure modes of longevity drug promises, and an argument for concentrating on living well rather than on living longer.

  6. #KnowledgeByte: Negligible #Senescence is a term that describes organisms that don't show signs of biological aging, such as reduced reproductive capability, functional decline, or increased death rates with age.

    It can also be described as a similar term to biological #Immortality, which means that an organism isn't more likely to die as it gets older.

  8. 📃New paper in Ecology letters 🐦 by ‪Bertille Mohring et al.

    Life-history trade-offs and #senescence in black-browed #albatrosses from Kerguelen and Bird Island

    Black-browed #albatrosses breeding in more variable environments display slower life histories (slow, late-onset reproductive senescence) and greater among-individual variation in life-history strategies

  10. Cellular #senescence is a biological paradigm in which a unique subpopulation of cells permanently and irreversibly stops dividing but evades apoptosis (programmed cell death). Instead of dying off, these arrested "zombie cells" remain metabolically hyperactive and linger within mammalian tissues.

  17. Scientists Have Discovered a Special Type of Immune Cell That Slows Aging

    Researchers have just discovered a way to destroy harmful 'senescent' cells that accumulate with age and ramp up the kind of tissue damage and inflammation that slowly brings life to a grinding halt.

    The team found that CD4 T immune cells transform into assassins of the damaging tissues when biological aging is detected in the body.

  19. Cellular Senescence in Health, Disease and Aging: Blessing or Curse? by Markus Riessland, 2021

    When Hayflick and Moorhead coined the term “cellular senescence” (CS) almost 60 years ago, this phenomenon was understood as a mechanism, usually induced by activation of the DNA-repair machinery, to prevent uncontrolled proliferation.

    Originally developed for organ transplantation to prevent immune rejection, previous research has found that, at non-#immunosuppressive doses, #rapamycin can mitigate cellular #senescence.

    "rapamycin provides direct #genomicprotection in human immune cells and may support healthy aging, offer benefits after clinical #radiationexposure, and could even address risks from #cosmicradiation during extended #spacetravel."

One reason there might be a correlation between old vines and great wines is that at successful vineyards they don't rip up their vines ... so the vines just get older. #wine #vineyard #grapes #alcohol #vitis #senescence #statistics daily.sevenfifty.com/the-scien

  27. Mutation accumulation theory (Evolutionary biology 🧬)

    The mutation accumulation theory of aging was first proposed by Peter Medawar in 1952 as an evolutionary explanation for biological aging and the associated decline in fitness that accompanies it. Medawar used the term 'senescence' to refer to this process. The theory explains that, in the case where harmful ...

  28. Why Some #Animals Live for Only Days and Others Live for Thousands of Years
    #Scientists are studying why some species live so much longer than others.
    Some species of #turtles, #fishes and #salamanders, for instance, don’t show any signs of degeneration or #senescence as they grow older. If they didn’t die of predation, accidents or infectious disease, they could live extremely long lives, Magalhães says.

  30. A quotation from Ella Wheeler Wilcox

    Let mine not be the saddest fate of all,
       To live beyond my greater self; to see
       My faculties decaying, as the tree
    Stands stark and helpless while its green leaves fall.
       Let me hear rather the imperious call,
       Which all men dread, in my glad morning time,
    And follow death ere I have reached my prime,
    Or drunk the strengthening cordial of life’s gall.
    The lightning’s stroke or the fierce tempest blast
       Which fells the green tree to the earth to-day
    Is kinder than the calm that lets it last,
       Unhappy witness of its own decay.
       May no man ever look on me and say,
    “She lives, but all her usefulness is past.”

    Ella Wheeler Wilcox (1850-1919) American author, poet, temperance advocate, spiritualist
    Poem (1882), “Uselessness,” Maurine and Other Poems (1882 ed.)
